MACHINE FOR PARING CURLED EDGES OF HAT-BRINIS.

SPECEFICATION forming part of Letters Patent N0. 587,943, dated'August10, 1897.

Application filed December 2l, 1896. Serial No. 616,484. (No model.)

To all whom it may concern.-

Be it known that I, CARL EICKEMEYER, a citizen of the United States,residing at Yonkers, in the county of Westchester and State of New York,have invented certain new and useful Improvements in Machines for Paring the Edges of Hat-Brims, of which the following is a specification.

This invention relates to improvements in the machines for paring theedges of hatbrims for which Letters Patent were'granted to RudolfEickemeyer, llo. 317,324, dated May 5, 1885, and No. 386,457, dated July24, 1888. The machines described in these patents, while answering tosome extent the purposes for which they were designed, did not meet,Without complicated changes, the requirements in paring the edges ofhat-brims of various styles of curl. Hats whose curls are the same atthe front and sides, as so-called flat curls, could be clamped and paredby the machine shown in the later patent, but where the curl is heavy orthick on the sides not only the clamps were, but also the rotary cutterwas, of little use. Unless the brim was wedged up in the front and rearof the hatbrim, so as to make the path of the edge of the curl lie in ahorizontal plane, the cutter would not work properly. My im provedmachine is designed to obviate this difficulty, as it permits the paringof the edge of the hatbrim without requiring the edge to be leveled byWedges by the use of a clamp by which the hat can be centered withoutthe aid of the central chuck heretofore used. The inside faces of theclamps are knurled, so as to hold the outside edge of the curl rigidlyin position, while the rotary cutter follows the edge of the brim and isadjustable to curls of any size from a iiat curl to the largest curlrequired. The mechanism for lifting the rotary cutter is operatedautomatically with the rotation of the hat bed-plate, on which the hatis pressed while being clamped. The slight pressure enables the hat tobe clamped with its curl perfectly symmetrical on all sides. The path ofthe rotary paring-knives can be changed in one adjustment by the use ofa main cam and suitable levers to full quarters, regular oval, orcut-out quarters on the hat-brim edge. By throwing the cutter out ofcutting position when placing a hat on the bed-plate and clamping itthereto an eccentric operated by a crank is employed, said crankcarrying in its interior a locking-pin which locks the cutters either intheir outward orin their cutting position.

In the accompanying drawings, Figure l represents a vertical centralsection of my improved machine for paring the edges of hatbrims, inwhich one-half of the hat` is shown in clamped position, with the rotarycuttingknives in position for operation, while the knurled faces of theclamps are shown on the other side of the elevation. Fig. 2 is a planview of Fig. l. Fig. 3 is a side elevation of the cutter-supportin gspindle and cross-head, partly in section and with bed-plate, ovalcam-plates, and cutting knives removed. Fig. 4 is an end elevation of myimproved machine, taken from the opposite side to that shown in Fig. 3;Fig. 4, a sectional detail of parts of Fig. 4. Fig. 5 is a plan view,with parts broken away, showing the cams, camholders, and forkedcam-roller carriers and other accessories.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a hat after the brim edge of thesame has been cur1edover a matrix in the curling-machine and the top ofthe edge ironed and set on a top-ironing and brim-edge-setting machine.After the matrix has been removed from the curl the hat a is placed on aclamping-plate a', which is fastened to a circular plate a2 by means ofscrews a3. The circular plate a2 is slotted to carry a cross-head a4,which in turn is supported on a vertical shaft a5. Between theclamping-plate a and circular plate a2 is interposed a circularcam-plate a, which is operated by a handle-lever a7 and clamped by athumb-nut as in connection with a bolt co9 and arc-shaped guide-slot@10in clampingplate a. The circular cam-plate a operates theclamping-fingers au, which are so improved that in connection with theparingknives the hat is properly centered Without the use of a centralchuck or curl-supporting wedges. The clamping-iingers au increasegradually in height from -the plate a as the curl of the brim becomeslarger or thicker to ward the sides of the curl and decrease graduallyfrom the sides toward the opposite end IOC of the curl. The clam ping-lingers-are knurled on their inner faces and clalnp the briin on the outerside. They are adjustable to any oval by set-screws @12, which arecarried by supports @13, that are in turn attached to crossheads C011,guided in radial slots @L15 of the circular cani-plate d6.

'The vertical spindle a5 carries at itslower end a cam Z9, below whichand forming a part of the saine are horizontal rails which forni guidesfor a cam-roller fork ZJ, that carries at its outer end a roller Z92,which turns on a bolt Z93, that is carried by a hub at the outer end ofthe fork Z9. On the hub of the fork presses a rod Z94, which is carriedby a double bracket Z95, said bracket being rigidly fastened to a shaftZ96 by means of clamping-screws Z97. The shaft Z96 forms the fulcrurnfor the double bracket Z95, which carries at one end a screw Z98, bywhich the cam-roller b2 can be released from the cam Z9, if desired. Theshaft Z96 is su pported inbearings of the brackets c c, which extendlaterally from the main frame c. The longitudinally-shifting rnotion ofthe shaft Z91 in its bearings c c is prevented by a collar 199, appliedby a set-screw to one end of the shaft, adjacent to one of the bracketsc, and by the hub of a lever Z910, that is attached by setscrews to theopposite end of the shaft Z96, adjacent to the other bracket c', asshown in Fig. 5. The outer end of the lever Z910 carries a pivot-pinZ111, which forms the bearing forthe lower end of a knuckle-joint Z912,to the upper end of which is pivoted a link 511, that is slotted at itsupper end Z915. To the slotted upper end Z915 of the linkZ911is'clarnped a pin 1916 by means of a thumb-nut Z917 and washersZ918, that are interposed between the slotted end Z915 and thethu1nb-nut Z91.7 and between said slotted end and a shoulder on thethreaded pin Z916, as shown in detail in Fig. 4. The pin Z911 furnishesa bearing for a clamp Z919, the angevof which laps over the slotted endof a lever Z920 and is pressed against the same by a sleeve Z921, whichis knurled at the out'- side, that it can be readily taken hold of inscrewing the interiorly-threaded sleeve on the threaded shank of theclamp Z919, whichcarries the head of the pin Zils. The lever Z920 turnson a pin Z922, which is supported by brackets c4, projecting from anupright frame c1, as shown in Fig. l. The forward end of the lever Z920is provided with a double fork Z928. (Shown in Figs. l and 2.)

The vertical spindle a5, located below the clamp-plates, carries abovethe cam Z9 a second cani d, below which, similar to cam Z9, arehorizontal surfaces which form guides for a second cam-roller fork d',that carries at its outer end a roller-d2, that turns on a bolt d3,carried by a hub on the end of the fork d. Against the end of the hub ofthe fork presses a rod (Z4, which is supported by a double bracket d5,said bracket being rigidly attached to a shaft d6 by means of bolts CF.The shaft d6 forms the fulcruin or rock-shaft for the bracket d, whichcarries a set-screw d8, to

which a wire or cord c is attached that passes around a grooved pulley con the rod Z91 and over a grooved pulley e2, carried by the frame c2. Tothe end of the cord e below the pulley e2 is attached a weight w, asshown in Fig. 4. The weight w exerts pressure on both double brackets b5and d5, so that the camrollers b2 and d2 are constantly kept in contactwith the faces of the cams Z9 and d, except when the screw Zas is usedincases in which the brim edges of flat or nearly fiat curls have to bepared. v

The rock-shaft d turns in bearings of a bracket c1-and a boss c3 on themain frame c2. The shaft d6 is prevented from shifting in longitudinaldirection by a collar dg, applied by a set-screw to one end of theshaft, and by the hub of a slotted lever d10, applied by setscrews tothe opposite end of the shaft, as shown in Fig. 5. To the slotted leverd10 is clamped a pin e211, which is provided with a collar that isshiftable in the slot of said lever and that can be clamped inanydesired position in the same by a thumb-screw d12 and washer d13. Theopposite end of the pin e111 forms the bearing for the end of a link d,which is shown in Figs. 3 and 4 in its iniddle or vertical position, inwhich position the slotted lever d10, although constantly in vibratorymotion, does not affect the movement of the rotary cutter, so thatconsequently the brim edge is pared to a regular oval. Should thequarters requirecu tting or be left full, the lower end of the lever c14 isV swung to one side or the other in the slot of the lever d10 andclamped at the desired point, according to the amount to be taken oft'or according to the amount to be left on the quarters of the hatbriinedge.

At the upper end of link d is a knucklejoint d15, the lower pin d'1 ofwhich serves as a pivot for the link d14. The upper pin d of theknuckle-joint C115 forms, the pivot for the arm of a cranked lever d,which is fulcrunied to a transverse pin d1, supported by brackets c5,said brackets forming a part of the vertically-movable frarne c7. Thecranked lever CZ1S has a downwardly-extending arm which is connected bya pivot-pin d20 with a. link C121, which is strapped to an eccentrice122 on a shaft CPS, that is supported in bearings ofrearwardly-extending brackets a8 of a lever-frame C10, which is providedwith bearings c11 and C12 for an inclined spindle 013, to the lower endof which the cutter-head c1l is applied. To the opposite end of theshaft 0123 is applied a crank-handle 24, which carries a spring-pressedlocking-pin C125, to the end IOO IIO

of which is applied a kn urled wheel CPG. The

ylocking-pin (F5 is pressed into either one of to be turned through anangle of one hundred and eighty degrees until the locking-pin LZ25engages in the rear hole d20.

Tothe inclined spindle G10 is splined a pulley cd15 in the usual manner,which enables the spindle to have a slight longitudinal movementindependently of the rotary motion transmitted to it by a cam-belt froma counter-shaft ci? and fast and loose pulleys 010 and C17. The inclinedspindle C13 carries the collars C18 and 010 at its upper end, betweenwhich is located agcross-head c20,'which in turn carries the guides 021,that prevent both the rotary movement and the longitudinally-shiftingmotion of the same independently of the guides or the double fork of thelever Z120.

The lever C10 is fulcrurned by suitable bearings to the conical ends ofscrews 022, about which it can be turned independently of the cross-head020 and the double fork Z323 of the lever` Z920, the guides 021 of whichare so constructed as to allow of a sliding movement radially withrespect to the axis of the screws 002. The frame c7 is verticallyadjustable for the purpose of permitting the changing of the initialposition of the cutter-head. The adjustment of frame cT is accomplishedby a screw 023, having a hand-wheel C04 in the upper part of the uprightframe c7. The frame c7 is firmly clamped after adjustment by means ofbolts 020, which engage slots of the bracket-frame C27, that carries thecountershaft 015.

The adjustment of the oval mechanism so that the rotary cutter withrelation to the hatbrim edge describes the desired ovalis accomplishedby changing the relation of the axis of the vertical shaft a5, which hasits vertical bearing in a hub carried by a plate K2, to that of thecenter of the circular guide K on plate K. Said circular guide K forms abearing for a curved cross-head K3, the concentric surfaces of whichengage in corresponding slots of the circular plate a2. The plate a2 isalso slotted to form guides for the crosshead, to which motion is givenby the curved cross-head, which is tangential. The said resultantmotion, which is transmitted to the circular plate a2 by means of thetwo crossheads K0, produces the desired ovals, the eccentricities ofwhich 'are proportional to the distance between the axis of the verticalshaft d5 and the axis of the circular guide K, which, when these twoaxes coincide, reduces the oval to a circle. The bed-plate a' beingcarried rigidly with the circular plate a2, the desired oval motion istherefore transmitted to the same. The proper adjustments are effectedby means of a knurled hand-wheel K4 on a screw K5, having bearing in lugK0, which is carried by the plate K2. The screw K5 engages with the threads in lug K0, carried by plate K, and the axial motion of said screwis prevented by collar KTand the wheelhub. The position of the describedoval is adjustable by means of a hand-wheel Z,

mounted on shaft Z', which has a bearing in the lug Z2, carried by plateK2. ment of shaft Z', which carries screw-threads on its end, isprevented by a collar on the one side and the wheel-hub on the other.screw-threaded portion of shaft Z engages with the threads in the lugZ0, carried on the end of a boh'J which is rigidly fastened to the mainframe of the machine.

The machine being adjusted for the required oval the lever Z215 isclamped in the required position with regard to the lever Z920 so as tolift the rotary cutter to correspond to the thickness of the c url to bepared. The desired style of quarters is produced by swinging the leverCZM to its required position and clamping it at the same time by meansof thumb-screw d1?. The proper adjustment being made and the rotarycutter being in its released position the hat to be pared is clamped byturning the lever a7 and is held in the clamped position by thumb-wheela8.

The rotary cutter is then swung into its aeting position by removing thelocking-pin cZ25 from the hole CZQS (shown in Fig. l) and replacing thelocking-pin in av corresponding hole arranged at an angle of one hundred`and eighty degrees from the same, thereby placing the cutter in theposition shown in Fig. 1. By moving the plate K2 by means of thehandwheel Z the hat-brim edge is moved to the cutting position. Furtheroperation of the machine is merely the quick movement of the bed-plate aby hand through one revolution, during which revolution the hat-brimedge has been automatically and at the same time symmetrically pared, asdesired. The cutter is then shifted to its released position, and by asimple reverse operation to that of clamping the hat is unclamped andthe machine is ready to receive the next hat of the same style withoutany further adjustment.

Having thus described my invention, I claim as new and desire to secureby Letters Patent` l. In a machine for paring the edges of hatbrims, thecombination of a rotating hat-bed, adjustable clamping-fingers arrangedthereon, an axially-movable spindle provided with a rotary cutter, andmeans for imparting a longitudinally-shifting movement to the cutter,independently of the rotary motion, substantially as set forth.
